Yeah I didn't mean to imply you could get work out of it, just that it's a system with zero dissipation, so it would seem to be a perpetual machine "of the third kind" as referenced by the post above. (If you don't count the work required to maintain low temperature, of course, which I don't think you should since you could place the device way out in intergalactic space where it would attain a temperature near 2.7K without you having to do any work to maintain it.
